問題描述
我有一個屏幕的 3 種狀態的片段；添加、編輯和查看.在添加中，我創建一個實體并保存它.下次我在查看模式下打開它并使用
I have fragments for 3 states of a screen; Add, Edit and View. In Add, I create an entity and save it. Next time I open it in View mode and set the entity name using
EditText entityName = (EditText) view.findViewById(R.id.entityName);
entityName.setText(entity.getEntityname());
我從查看模式單擊編輯按鈕以打開編輯模式.我在這里更改實體名稱并保存.這讓我回到了視圖屏幕.但我發現實體名稱沒有更新.我調試并發現 entity.getEntityname() 具有正確的值.我不確定為什么編輯文本沒有采用新值.
I click on the edit button from View mode to open the Edit mode. I change the entity name here and save it. This brings me back to the view screen. But I find the entity name is not updated.
I debug and found that entity.getEntityname() is having correct value. I am not sure why the edit text does not take new value.
有什么想法嗎?
注意:我使用的是安卓 2.2 版
Note: I am using android version 2.2
推薦答案
EditText 似乎在重置 onCreateView 中的文本時出現問題.所以這里的解決方案是重置onResume中的文字.這行得通.
The EditText appears to have an issue with resetting text in onCreateView. So the solution here is to reset the text in onResume. This works.
onActivityCreated 也有問題.我在 onStart 中重置了 edittext 的內容，它可以工作.[感謝@savepopulation]
Also there's an issue in onActivityCreated. I reset edittext's content in onStart and it works. [credits to @savepopulation]
